title: Inhibition of cardiac sympathetic nerve activity during swallowing evoked by laryngeal afferent stimulation in the cat.
abstract: Spontaneous swallowing or the buccopharyngeal phase of swallowing evoked by electrical stimulation of the superior laryngeal nerve was accompanied by a pronounced decrease of sympathetic activity in the cardiac nerve. This reduction of sympathetic activity was not related to other influences such as postinspiratory inhibition or baroreceptor-mediated inhibition. Intracellular recordings from sympathetic preganglionic neurones revealed hyperpolarization during the buccopharyngeal phase of swallowing, possibly due to postsynaptic inhibition.
